Background: Unilateral retinitis pigmentosa is a retinal dystrophy affecting only one eye, the fellow eye being affected neither functionally nor in fundus appearance. There are relatively few cases of unilateral retinitis pigmentosa being followed for more than 5 years.
Case: An 18-year-old woman complaining of blurred vision of left eye was found to have left visual field concentric contraction. Because the right eye was unaffected electrofunctionally and in fundus appearance, there was a suspicion of unilateral retinitis pigmentosa. We tracked her for 8 years and, because the right eye remained unaffected, we diagnosed unilateral retinitis pigmentosa of left eye.
Conclusion: We report a case of unilateral retinitis pigmentosa. It is reported that the healthy fellow eye of patients with unilateral retinitis pigmentosa developed bilateral retinitis pigmentosa after 10 years, consequently, this case needs further follow-up.

Predicting branch retinal vein occlusion development using multimodal deep learning and pre-onset fundus hemisection images.

Branch retinal vein occlusion (BRVO) is a leading cause of visual impairment in working-age individuals, though predicting its occurrence from retinal vascular features alone remains challenging. We developed a deep learning model to predict BRVO based on pre-onset, metadata-matched fundus hemisection images. This retrospective cohort study included patients diagnosed with unilateral BRVO from two Korean tertiary centers (2005-2023), using hemisection fundus images from 27 BRVO-affected eyes paired with 81 unaffected hemisections (27 counter and 54 contralateral) for training.

Department of Ophthalmology, Fuyang Hospital Affiliated to Bengbu Medical University(Fuyang People's Hospital), Fuyang, 236400, Anhui Province, China. Electronic address:
Purpose: To evaluate optic disc and macular microvasculature changes in children with anisometropic amblyopia before and after treatment.
Methods: In all, 60 children with unilateral anisometropic amblyopia between the ages of 6 and 12 were randomly selected from the ophthalmology clinic of Fuyang People's Hospital, while 60 children with non-amblyopia in the same age range were randomly selected as a normal control group. The right eye was uniformly taken in the control group with at least 6 months of follow-up.

Purpose: The purpose of this study was to analyze choroidal thickness (CT), along with macular thickness (MT), peripapillary retinal nerve fiber layer thickness (RNFLT), and macular vascular density (MVD) using swept-source optical coherence tomography (SS-OCT) in children with unilateral amblyopia, and compare the same with normal fellow eyes and normal eyes of normal children before and following occlusion therapy.
Materials And Methods: This was a prospective, longitudinal study of 60 children (4-18 years); 30 children had unilateral amblyopia and remaining 30 were normal. Group 1 consisted of 30 amblyopic eyes of children with unilateral amblyopia; Group 2 consisted of 30 fellow normal eyes of Group 1; Group 3 consisted of normal eyes of normal children.
